His latest company, Canogle, owns Point, a smart phone tour guide that is currently available on trails throughout the Bay Area including the U.S. National Park Service and our own Fernandez Ranch. Other companies include owner-side construction management software and business-to-business management solution software with clients including the US Department of Transportation, the Department of Veteran Affairs, the U.S. Olympic Committee and numerous public agencies and school districts throughout the United States. Before becoming an entrepreneur, Arthur was a practicing licensed civil engineer. He earned his BS from UC Berkeley after emigrating from Sierra Leone, West Africa.

Today Arthur is expanding his latest venture, volunteering as a soccer coach for CCYSL, and mentoring young men into adulthood. He and his wife are homeschooling their three daughters in Hercules.



Bill Wadsworth, moved to Pleasant Hill when he was six years old and spent hours exploring the neighboring fields at a time when Sun Valley Mall and today’s freeways were just someone’s dream. Contra Costa County has been his home ever since. He graduated from UC Davis and met his wife, Ginger, there. Both are active volunteers in Orinda where they have lived for the past 32 years and raised 2 sons. They walk daily on the 300+ acres of open space behind their house. After a long career in finance and accounting for Bay Area-based engineering companies, Bill reduced his work schedule to give him more time to enjoy gardening, reading, hiking, sports, and other volunteer interests. Bill is currently president of the Orinda Park and Recreation Foundation that supports many recreation activities, facilities, and open space acquisitions. He has served on the JMLT Audit and Finance Committees in recent years. He also assists researching, editing, and promoting Ginger’s award-winning biographies and nature/environmental-related books for children; plus they enjoy traveling for both research and fun. They spend over a month each year in the beautiful Anza-Borrego desert in Southern California where their one-room house is surrounded by thousands of acres of state park land. Do you sense a thread in Bill’s life that is leading him to become more involved with JMLT?


Immediate Past Chair

Dawn Block grew up in a New York inner-city housing project, where she had little exposure to natural elements, (she saw her first cow at age 12 in the Bronx Zoo). But once she finished her degree at Queens College, Dawn was determined to gain a broader world view. Following a year as a volunteer teacher overseas, she returned to the States and bypassed New York altogether, landing in sunny California. She loves to travel and is known to venture pretty far off the beaten path for the sake of viewing amazing wildlife and scenery (like in Antarctica and Madagascar). She’s a tree-hugger at heart with a passion for hiking. Volunteer-wise, she’s past-president of the Pleasant Hill Chamber of Commerce and has previously served on other non-profit boards of directors. When she needs to earn a living, she runs her own company — Block Talent Partners — which specializes in executive search and human resources consulting for technology startups in the Bay Area. She’s a natural headhunter and people connector who has the chutzpah to raise money for causes dear to her heart. Dawn is married to the love of her life, Dr. Michael Harris. She has two extraordinary daughters: Lindsay is a professional track athlete (and aspiring Olympian) for Nike; Ashley is a doctoral student at Georgia Tech, pursuing bioengineering and stem cell research.

Chuck has been a member of the JMLT Stewardship Committee and was named Volunteer of the Year in 2010.

He has been a member of the Sierra Club since graduating from the University of California, Berkeley, and has served on the West County Executive Committee for a number of years. He was very active with saving Franklin Canyon from development and with working toward its eventual purchase by the Land Trust. He was one of the original signers of the Save Franklin Canyon Initiative, which set this process in motion. For this and other work with the Sierra Club he received one of its esteemed Volunteer of the Month Awards. At a recent Fresh Aire Affaire, Steve adopted an acre of the canyon as part of his long-term commitment to helping preserve this open space. In Hercules Steve served on the Vision Plan Committee for Refugio Creek and currently he is the Chair of the Community and Library Services Commission, and in this capacity he serves on the Contra Costa County Library Commission. During the summers he works as a school site administrator with UC Berkeley’s School of Education’s Academic Talent and Development Program. When asked about what he wants to do in retirement he always says, "Now I will have some "off-season" time to travel and time to volunteer with the John Muir Land Trust!"



A life-long resident of the East Bay and longtime resident of Danville, Eileen McCauley has a deep love of the outdoors. Growing up in Berkeley she explored Tilden Park and Lafayette Reservoir with her many siblings. Her summers on Tomales Bay were spent sailing and enjoying the National Seashore at Point Reyes. She has hiked the Rim to Rim Trail in the Grand Canyon, trekked the Camino in Spain, and cycled the wine country in France. She took special joy in introducing her two sons to the outdoors on local trails and through their Boy Scout adventures. Now retired, Eileen enjoys traveling and cycling the world—always upon her return to appreciate how blessed we are to live in such a majestic area. Eileen embraces the philosophy of smart growth and believes in developing much-needed housing while also retaining the rural character of the area that we all love so much. After graduating from UC Berkeley, Eileen attended USF Law School and spent her career working in Civil Litigation and Real Estate Law. She is devoted to volunteering and enhancing the lives of others. Children are our future, and for more than a decade, Eileen has tutored children who are challenged by reading due to a processing disorder. She currently tutors for San Ramon Valley Unified School District. She also has a passion for working with foster youth and is inspired by JMLT’s partnership with Family Harvest Farm and its work with foster youth.

Ted C.


Ted Radosevich spent his early years in Richmond before his family moved to the Alhambra Valley in Martinez. His parents bought land on the former John Swett Ranch and built their own home, settling there in 1958 with Ted and his two brothers. The home is still the family focal point, where he celebrated his 56th consecutive family Christmas dinner this last year. Ted graduated from the University of California, Berkeley and then obtained his law degree at Harvard Law School. He worked for the United States Department of Justice in Washington, DC for several years before returning to the Bay Area. Back home, he practiced law and became a partner in a major San Francisco law firm with a focus on real estate and environmental law. In 1989, he was hired as the General Counsel for the East Bay Regional Park District, where he served for nearly 25 years before retirement. During his tenure, he supervised all major legal issues and litigation facing the District and played a role in the acquisition of nearly 50,000 acres during his 25 years. In his dual role as an Assistant General Manager, he provided policy and legal guidance on four successful ballot funding measures, and overall budgetary and financial input which helped to secure a AAA bond rating for the Park District (which Ted notes is higher than the rating of the United States). At Harvard Law School he met, and later married Stephanie Smith, who continues practice in legal fields of dispute resolution and negotiation while also teaching at Stanford Law School. Their two now-adult sons hiked and ambled over Contra Costa open space for years. Preserving and expanding this type of opportunity and heritage for the future has drawn Ted to serve on the John Muir Land Trust.
